Desenvolvimento de uma interface móvel de controle e monitoramento de reações químicas baseadas em titulação por termometria.

Abstract

This paper has the purpose of developing a control and monitoring graphical interface for a thermometric titration system by use of a smartphone. For such, a Raspberry Pi microcomputer was utilized to perform the reading of an infrared pyrometer and the transmission, through a Bluetooth connection, of the obtained temperature data to an Android device. In this device, the developed application was utilized to receive the temperature values in real time and to show them on a line chart. As they are received, the values are also registered in a database so they can be later visualized and even shared. At the end of the development it was possible to assert that the use of a remote equipment to monitor temperature variation over time is viable and can be obtained at a low cost if compared to utilizing equipment such as infrared video cameras.
